Research Interests

My research topics focus on the exploration of planets inside and outside of our solar system. I have been involved in NASA’s Cassini Mission to Saturn and the Juno Mission to Jupiter. I use numerical models, ground-based telescopes, and data collected from space missions to further our understanding of the physical properties of planets. Specifically, I’m interested in fluid motions, including the atmosphere, ocean, and convection powered by the internal heat of a planet. Planets provide unique natural laboratories that are unattainable on Earth. By studying the planets, we learn the fundamental physics, the past, and the future of the home we live on.
